This research reports age and gender differences in cardiac reactivity and subjective responses to the induction of autobiographical memories related to anger, fear, sadness, and happiness. Heart rate (HR) and subjective state were assessed at baseline and after the induction of each emotion in 113 individuals (61 men, 52 women; 66% European American, 34% African American) ranging in age from 15 to 88 years (M = 50.0; SD = 20.2). Cardiac reactivity was lower in older individuals; however, for anger and fear, these age effects were significantly more pronounced for the women than the men. There were no gender differences in subjective responses, however, suggesting that the lower cardiac reactivity found among older people is dependent on gender and the specific emotion assessed.

This study examines the life course of 2 independent components of adult affective development, 1 aimed at differentiation and complexity, the other aimed at optimization and positive emotional balance. These 2 components are predicted to have different developmental trajectories over the adult life span and to become related in a compensatory fashion under conditions of resource restrictions, such as those related to late life. Using individual growth curve estimation, we modeled 6-year longitudinal changes in the 2 components in a total sample of 388 individuals ranging in age from 15 to 88 years. As predicted, initial level of affect optimization was positively associated with age up to late middle age with a subsequent leveling off; individual rates of change were found to decelerate with age up to age 60 years and accelerate again around age 80 years. For affect complexity, initial level of affect complexity was positively associated with age up to age 45 years and negatively associated with age from then on, whereas individual rates of change were negatively associated with age, and this association tended to get stronger with age.

Examination of physiological coregulation among marital partners suggests a dynamic interplay between partner physiology. Further, attachment dimensions of anxiety and avoidance mediate this coregulation during conflict. This study examined the role of attachment and race in predicting physiological coregulation for mothers and their adult daughters during emotional discussions. A sample of 23 African American and 17 Caucasian mother-daughter pairs (aged 26 to 83) completed interview sessions and Relationships Questionnaires. Pairs engaged in discussions (neutral, conflict, happy), while monitoring heart rate. HR difference scores were computed between pairs (bps; 0 meant no difference). Multiple Regressions revealed attachment anxiety and avoidance predicted HR variation between pairs for the neutral and happy discussions, differently by racial group (F(7,33)=3.297, p < 0.01). For African American women, increased anxiety predicted increased HR variation during neutral and happy discussions, whereas for Caucasian women, increased avoidance predicted increased HR variation. However, during conflict anxiety singularly predicted increased HR covariation (b = 5.03, p = 0.01), for both groups. Low anxiety and low avoidance predicted physiological coregulation (lower HR variance between pairs). Increased anxious attachment predicted partner dysregulation (increased HR variation between pairs) across all 3 discussions, moderated by avoidance for the Caucasian women. Results suggest attachment plays a role in regulating physiology under emotional stress, and that there may be important cultural differences in this relationship. Further examination will explore the dynamic interplay between attachment and physiological coregulation across adulthood and later life.
